Area code 256

Where area code 256 is

NANPA lists 256 as an in-service geographic area code for Alabama, first put into service on March 23, 1998. It is an overlay: 256 and 938 cover the same territory, so neighbors on the same street can have different area codes. It is in the Central time zone. The places with the most assigned exchanges include Huntsville, Decatur, Anniston, Gadsden, and Cullman. By population, its largest named places are Huntsville, Madison, Decatur, Florence, and Gadsden.

Dialing 256 numbers

According to NANPA's dialing-plan data, local calls within 256 are dialed as ten digits (area code plus number) and toll calls as 1 plus ten digits. Because local calls need the area code, business cards, signage and website copy should always show the full ten-digit number. NANPA's dialing-plan note for this code reads: "1+10 digit permissible at service provider discretion"

Phone companies in area code 256

52 carriers hold the 786 central office codes assigned in 256. Bellsouth Telecomm INC d/b/a South Central Bell Tel has the most, with 180 (23%). 579 of the codes (74%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. The code holder is not necessarily the carrier serving a given number today, since numbers can be ported between providers.

Local calling areas in 256

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 256 has codes in 92 rate centers. Rate center names in the file are abbreviations; where one matches a Census place, the table links to that city's local-number page.
